Characterization of Structure, Properties, and Energetic Performance of a 1:1 Ammonium Dinitramide‐3,4‐Diaminofurazan Cocrystal

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...

Resource redeployment as an entry advantage in resource‐poor settings

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Scarcity of productive factors poses a challenge for firms entering underdeveloped regions. We theorize that incumbent firms can overcome scarcity of skilled human capital in local labor markets by redeploying workers from existing units.

Launch support: Managing complementor bottlenecks in the disruptive innovation of small satellites

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Through both qualitative and quantitative analyses of large‐rocket providers' support for small‐satellite manufacturers before the emergence of small rockets, we examine how disruptors to an incumbent ecosystem gain support from complementors of the incumbent technology.
